LARGEST LIQUID HYDROGEN DEWAR (WITH NO BOIL-OFF LOSSES)

Isotherm Energy is under subcontract for design of the largest hydrogen dewar tank in history at the NASA Kennedy Space Center (KSC). As previously reported by NASA, the new dewar will hold well over one million gallons of liquid hydrogen and is 50% larger than the current record holder that supported space shuttle launches for 30 years (see below).

A primary focus of Isotherm Energy’s support is the analysis, design and integration of a refrigeration system that eliminates hydrogen loss during storage. The successful design and operation of a long-duration liquid hydrogen storage system at this scale with zero boil-off, liquefaction and densification capabilities has far reaching implications beyond the space program.

HYDROGEN ENERGY-WATER SYSTEM ARCHITECTURE

Overview

Development of a hydrogen-based energy storage system architecture that also produces clean water from various non-potable sources (e.g. seawater, wastewater, etc.). The architecture will integrate the best existing and emerging technologies to optimize the system performance for wide ranging applications.

Features

Interfaces with any energy source that produces electricity

Uses seawater, wastewater, and other non-potable water sources

Compatible with biomass and other feedstocks containing hydrogen

Optimized hydrogen production and storage for specific applications

Supplies hydrogen for fuel cells, turbines, and other combustion processes

Heat recovery maximizes round trip efficiency

Benefits

Stores variable energy input for later use (e.g. solar, wind, etc.)

Produces potable water while generating electricity

Energy and potable water from locally available biowaste

Oxygen and other beneficial byproducts produced

Supports combined heat and power (CHP) operation

Scalable architecture for mobile and stationary systems

Applications

Microgrids and energy storage

Desalination and onsite water processing

Transportation systems

THERMAL-FLUID-ENERGY SYSTEM DESIGN TOOLS

Overview

Software design tools for thermal, fluid, and energy systems. Verified and validated models that enable rapid assessment of engineering trades for optimizing a baseline design. Capability to drop in existing components and subsystems to model integrated performance. Flexibility to integrate new technologies to explore impact on overall system.
